Alzheimer Award


medalEach year, the Associate Editors of the journal select the best article from the previous year's volumes. The awardee is presented the Alzheimer Medal, a 3" bronze medal with the likeness of Alois Alzheimer, and a cash prize of $7500. This yearly award is made possible by support from the Alzheimer's Research & Prevention Foundation and IOS Press.

Importance of Published Article
The NIA-AA criteria for “preclinical” Alzheimer’s disease (Sperling et al., Alzheimers Dement 7, 280-292, 2011) propose a staging method in which AD biomarkers follow an invariant temporal sequence in accordance with the amyloid cascade model: Stage 1 refers to amyloid accumulation only; Stage 2 refers to amyloidosis plus neurodegeneration; and Stage 3 requires both plus evidence of subtle cognitive decline. However, our study findings (Edmonds et al., J Alzheimers Dis 47, 231-242, 2015) did not conform to this sequence. We found that, among participants in the Alzheimer’s Disease Neuroimaging Initiative, neurodegeneration alone was 2.5 times more common than amyloidosis alone at baseline. For participants who demonstrated only one abnormal biomarker at baseline and later progressed, neurodegeneration was most common. Amyloidosis only or subtle cognitive decline only were less common—and equally common. Thus, the majority did not show amyloid positivity as the first sign of their eventual progression to MCI or AD diagnosis, suggesting that most individuals do not follow the temporal order proposed by NIA-AA criteria. In this article we also provide an operational definition of subtle cognitive decline that follows from our prior work on defining MCI via actuarial neuropsychological criteria (Bondi et al., J Alzheimers Dis 42, 275-289, 2014), and we offer a new approach to staging preclinical AD based on number of abnormal markers without regard to their temporal order. This method of characterizing preclinical AD is more parsimonious than the NIA-AA staging system and does not presume that all patients follow a singular invariant expression of the disease in accordance with the amyloid cascade model.
